for spraying.

It is one object of the invention to provide an etlicient means for effectually mixing the spraying materials before they are deposited in the main reservoir whereby to secure amoreuniform mix as well as to prevent clogging of the screen to the'discharge hose.

It is another object of the invention to provide a machine of the character indicated wherein a fluid jet is llillllZGd'lIl con unct1on with impeller means for mixing the spraying materials preparatory to depositing in the main reservoir.

It is also an obj oct of the invention to provide an auxiliary mixing system that will not only be extremely simple in construction and operation, but also one that may be quickly and easily added to any spraying outfit of the well known type without material alterations thereto. 7

In the drawing:

Figure 1 is a perspective illustration of a portion of a spraying outfit embodying my invention.

Figure 2 is a vertical longitudinal section through the same, parts being broken away.

Referring more particularly to the drawing, I show at 1 a well known form of tank or reservoir mounted upon a vehicle 2. The vehicle also carries a power plant 3 and a pump of any suitable type as at at. The discharge of the pump is indicated at 5 and the conduit connecting the tank and the pump at 6. The mixing propeller structure 7 in tank 1 is operated by means of a chain and sprocket connection 8 to thesh'aft 9 operated by the pump 4. The general structure indicated by the reference 10 is provided for filling the tank 1 from any suitable source of supply and is not described in detail, sinceno new features are embodied therein. At 11 is a small pipe extending from the discharge end of the pump to the top of the tank 1 and thence downwardly into the same and controlled by a valve as at 12.

0 In effecting my invention I first provide a tank 18 of any suitable dimensions but preferably soformed as to have a lower surface converging to a low point 14L where it may discharge into the main tank 1 through 5 a conduit 15 controlled by a'valve 16, the

tank being supported .upon the main tank 1 in any suitable manner as by blocks 17. An extension as 18 is provided on pipe 11 and fitted with a valve 19, the end of the" pipe terminating in an upwardly extending nozzle 20 inconduit 15 in such a mannoras to discharge central point. I I

At show ashaft mounted to rotate longitudinally of the tank 13 and having into tank 13 at its lowest and propellers 22 mounted thereon in such manner as to throw the liquid toward the 7 center of the tank over the jet or nozzle 20, the blades being oppositely directed to accomplish this purpose. This shaft is driven by means of a sprocket and chain connection 23 to theshaft 9. The tank 13 is with a filler opening at 24. Y

The operation, of the device may Vary somewhat according to the materials used. It the spraying is to be done with a soap solution, then the required quantity of soap (usually a thick, viscous mass) is. deposited in the tank 13 with some water, water havmg also been pumped'into tank 1. The machine is now put into operation and the contents 0]": the tank 13 is mixed by the propellers 22. At the same time the valve 12 may be closed and the valve 19 opened thereby permitting the pump to discharge a jet ofliquid from tank 1 into the tank13 in such a manner as to meet the liquid thrown toward the center of the tank by the propellers 22 and greatly increase the turbulence thereof. The mixture may be letinto the tankl by opening the valve 16, the jet operating to more thoroughly mix the-ingredients while the emptying process is going on.

:By this means the preliminary mixing reduces the soap to a thin solution, and then provided so I when it is discharged into the larger tank 7 it is quickly disseminated throughout the larger body therein by the propeller-mechanism. 7, insuring a spraying solution of the same strength both at the beginning and. ending of the spraying process.

. There the spraying material isof such a nature that it dissolves but slowly, the de sired quantity may be placed in the tank 18 after the tank 1 has been charged and ready for use, and with the valve16 closed the contents of the said tank may be subjected to i the churning action of the propellers 22 during the entire time required for using up the contents of tank 1. By means of this methodiof preparing the material a continus ous supply may be kept on hand ready for use Without the necessity of putting it through a long period of dissolving in barrels orfother containers as is 110W the case, especially When a crystalline substance like blue vitriol is used. It is to be understood, of course, that While 7 I have herein shown and described but one embodiment of the v invention, changes in term, construction and method I of arrangement and operation may. be made within the scope of'the appended claims.

Iclaim: 1. In combination, a tank for holding a spraying liquid, an auxiliary tank arranged 'thereabove, a Valve controlled conduit connecting said tanks, a pumping plant operatively mounted to pump liquid from the first tank, and "a conduit communicating Wltll'SillCl pumping plant and terminating in a nozzle positioned in said'first mentioned condnit'and above said valve and directed toward said second mentioned-tank.

2. In combination, a tank for holding a sara in li u'id an auxiliar tank ositioned thereover, an agitator mounted in the second tank and provided With propellers adapted to throw the liquid contents of the tank toward the center thereof, a valve controlled conduit connecting said tanks, apoWer plant operatively mounted to pump liquid'from the first tank and to operate said agitator,

and a conduitcommunicating with said yum )in )lant and terminatin in a nozzle HERBERT B. e 'rH IE,
